Fabian Reinartz	9c93f8f2aa	Fix various races ... This fixes different race condition encoutnered when running Prometheus. It reduces the overall performance in the synthetic benchmark a fair bit but has no indiciations of impacting a real-world setup notably.	8 years ago

Fabian Reinartz	ad5812d83a	Handle WAL corruption by truncating ... This adds handling for various corruption scenarios of the WAL. If corruption is encountered, we truncate the WAL after the last valid entry transparently and continue appending after the offset.	8 years ago

Fabian Reinartz	cb4dde7659	Fix WAL log recovery bug ... This fixes a bug where the last WAL file was closed after consuming it instead of being left open for further writes. Reloading of blocks on startup considers loading head blocks now.	8 years ago
Fabian Reinartz	55a9b5428a	Add separate head mutex ... Introduce a seperate mutex for the head blocks to avoid a race where a post-compaction reload may run between switching the DB's base mutex to create a new head block in an appender.	8 years ago

Fabian Reinartz	f734773214	Replace per-file locking with single PID lock file ... File locks have a multitude of problems that make them hard to use correctly. As they are just advisory, they are only meaningful to prevent accidents like running the same process twice. A simple PID file lock works reliably in those cases and is simpler.	8 years ago

Fabian Reinartz	1c80c33e72	Fix bug of unsorted postings lists being created ... The former approach created unordered postings list by either map iteration of new series being unsorted (fixable) or concurrent writers creating new series interleaved. We switch back to generating ephemeral references for a single batch. Newly created series have to be re-set upon the next insert.	8 years ago
